ABSTRACT

Abstract Objective We aim to describe an experimental model for studying femoral fractures in rats after exposure to ionizing radiation, demonstrating a way to apply a substance for analysis, the method for patterning fracture and irradiation, and how to evaluate its effectiveness based on radiographic studies. Methods We used 24 rats divided into 2 groups of 12 animals each. The STUDY group was exposed to ionizing radiation and treated with saline solution, and the CONTROL group was not exposed to radiation and was treated with saline solution. All animals were subjected to standardized fracture of the right femur that was fixed with intramedullary wire. The efficiency of the bone union was assessed by radiographic exam. Results Fracture healing was more efficient in bones not exposed to ionizing radiation (p = 0.012). All fractures met the criteria of being simple, diaphyseal, transverse or short oblique. Conclusion The experimental model presented is an efficient alternative for the study of fractures in irradiated bones in rats.


Resumo Objetivo Nosso objetivo é descrever um modelo experimental para estudo de fraturas de fêmur em ratos após exposição a radiação ionizante, demonstrando uma forma de aplicação de uma substância para análise, o método de padronização de fratura e irradiação e a forma de avaliação de sua eficácia com base em estudos radiográficos. Métodos Utilizamos 24 ratos divididos em dois grupos de 12 animais cada. O grupo ESTUDO foi exposto à radiação ionizante e tratado com soro fisiológico, enquanto o grupo CONTROLE não foi exposto à radiação e foi tratado com soro fisiológico. Todos os animais foram submetidos à fratura padronizada do fêmur direito e sua fixação com fio intramedular. A eficácia da consolidação óssea foi determinada por exame radiográfico. Resultados A cicatrização de fraturas foi mais eficiente em ossos não expostos à radiação ionizante (p = 0,012). Todas as fraturas atenderam aos critérios de serem simples, diafisárias, transversas ou oblíquas curtas. Conclusão O modelo experimental apresentado é uma boa alternativa para o estudo de fraturas em ossos irradiados em ratos.

ABSTRACT

RESUMO O presente estudo tem como objetivo avaliar o efeito da aplicação de diferentes concentrações de biossólido de lodo de esgoto, submetido a tratamento térmico, no estabelecimento de espécies herbáceas (aveia preta, ervilhaca e azevém) e nos atributos químicos e microbiológicos de um solo degradado pela mineração de carvão. O experimento foi instalado em área degradada pela mineração de carvão, localizada no munícipio de Treviso (SC), sendo os tratamentos compostos pelas concentrações de 0, 6,25, 100, 250 e 500 Mg ha-1 de biossólido, em parcelas de 2×2 m. Foram cultivadas espécies de aveia preta, ervilhaca e azevém de maneira consorciada, avaliando-se os parâmetros das plantas e os atributos químicos do solo nas profundidades 0-5, 5-10 e 10-20 cm. O biossólido proporcionou a elevação do pH do solo e o aumento dos teores disponíveis de P, K e carbono orgânico total e não influenciou na colonização micorrízica, na respiração basal do solo e na nodulação radicular. O uso do resíduo biossólido como substrato em áreas degradadas é uma alternativa para sua disposição final pela economia ao utilizá-lo como fertilizante, além dos benefícios ambientais, associados ao seu uso.


ABSTRACT This study aims to evaluate the effects of different concentrations of sewage sludge biosolid concentrations, submitted to thermal treatment, in the establishment of herbaceous species (black oats, vetches, and ryegrass) and in the chemical and microbiological attributes of a soil degraded by coal mining. The experiment was installed in an area degraded by coal mining, in Treviso/SC, with treatments composed of concentrations of 0; 6.25; 100; 250; and 500 Mg ha-1 of biosolids, in 2×2 m plots. Species of black oat, vetch, and ryegrass were grown in a consortium manner, evaluating the plant parameters and chemical attributes of the soil at depths 0-5, 5-10, and 10-20 cm. The biosolids provided improvements in soil fertility, such as pH elevation, increased levels available of P, K, and total organic carbon, in addition to not influencing mycorrhizal colonization, basal soil respiration, and root nodulation. The use of biosolid waste as a substrate in degraded areas is an alternative to its final disposal due to the economy when using it as a fertilizer, in addition to the environmental benefits associated with its use.

ABSTRACT

ABSTRACT: Microbial biomass is a driving force in the dynamics of soil organic matter, and microbial activity is an indicator of soil quality in agroecosystems, reflecting changes in management practices and environmental conditions. We evaluated the effect of monoculture and intercropped winter cover crops on soil chemical attributes, microbial biomass carbon (MBC), basal respiration (BR), metabolic quotient (qCO2), urease, β-glucosidase, and fluorescein diacetate (FDA) hydrolysis activity, as well as onion yield in a no-tillage system. Soil is a Typic Humudept, and treatments were control with spontaneous vegetation, barley, rye, oilseed radish (OR), OR + rye, and OR + barley. The soil was sampled (0-10 cm) five times between June and December. There were no differences among treatments for MBC and BR, and the highest values for those attributes occurred in June, when cover plants were in their initial stage. Although, qCO2 was not affected by any treatment, it varied among sampling periods, ranging from 0.62 to 10 µg C-CO2 mg-1 MBC h-1, indicating a low- or no stress environment. Cover crops had little influence on enzyme activity, but FDA was lowered in areas with single crops of barley and rye. Average onion yield in cover crops treatments was 13.01 (Mg ha-1), 30-40% higher than in the control treatment.


RESUMO: A biomassa microbiana é determinante na dinâmica da matéria orgânica do solo e sua atividade é um indicador de qualidade do solo em agroecossistemas, refletindo mudanças em práticas de manejo e em condições ambientais. Avaliou-se o efeito de culturas de cobertura de inverno, solteiras ou consorciadas, sobre atributos químicos do solo, carbono da biomassa microbiana (CBM), respiração basal (RB), quociente metabólico (qCO2) e atividade das enzimas urease, β-glucosidase e FDA, bem como o rendimento da cebola em um sistema de plantio direto. O solo é um Cambissolo Húmico alumínico, os tratamentos foram testemunha com vegetação espontânea, cevada, centeio, nabo forrageiro (NF), NF + centeio e NF + cevada. Realizaram-se cinco coletas de amostras de solo (0-10 cm) entre junho a dezembro. Não houve diferenças entre os tratamentos para CBM e RB, e os maiores valores para esses atributos ocorreram em junho, quando as plantas de cobertura estavam em seu estágio inicial. Embora o qCO2 não tenha sido afetado por nenhum tratamento, ele variou entre os períodos de amostragem, com valores entre 0,62 e 10 µg de C-CO2 mg-1 MBC h-1, indicando um ambiente de baixo ou nenhum estresse. As culturas de cobertura tiveram pouca influência na atividade enzimática, mas o FDA foi reduzido em áreas com cultivos solteiros de cevada ou centeio. O rendimento médio de cebola nos tratamentos com culturas de cobertura foi de 13,01 (Mg ha-1), mais alto que no tratamento controle.

ABSTRACT

SUMMARY OBJECTIVE: To evaluate the epidemiological data and available treatments for fractures secondary to radiotherapy treatment. METHODS: Identification of publications on pathological skeletal fractures previously exposed to ionizing radiation. RESULTS: The incidence of fractures after irradiation varies from 1.2% to 25% with a consolidation rate of 33% to 75%, being more frequent in the ribs, pelvis, and femur. The time elapsed between irradiation and fracture occurs years after radiotherapy. Risk factors include age above 50 years, female gender, extensive periosteal detachment, circumferential irradiation, tumor size, and anterior thigh location. The etiology is still uncertain, but cellular disappearance, reduction of bone turnover and activity were observed hematopoietic as possible causes of failure of consolidation. CONCLUSION: There is no consensus in the literature on the factors related to the development of fractures, with radiation dose, previous tumor size and periosteal detachment being suggested as potential factors.


RESUMO OBJETIVO: Avaliar dados epidemiológicos e tratamentos disponíveis para fraturas secundárias ao tratamento radioterápico. MÉTODOS: Identificação de publicações sobre as fraturas patológicas ocorridas em esqueleto previamente exposto à radiação ionizante. RESULTADOS: A incidência de fraturas após irradiação varia de 1,2% a 25% com taxa de consolidação de 33% a 75%, sendo mais frequente em costelas, pelve e fêmur. O tempo decorrido entre a irradiação e a fratura ocorre anos após a radioterapia. Os fatores de risco incluem idade acima de 50 anos, sexo feminino, descolamento periosteal extenso, irradiação circunferencial, tamanho do tumor e localização anterior na coxa. A etiologia ainda é incerta, mas foram observados desaparecimento celular, redução do turnover ósseo e da atividade hematopoiética como possíveis causas da falha de consolidação. CONCLUSÃO: Não há consenso na literatura avaliada sobre os fatores relacionados ao desenvolvimento de fraturas, sendo a dose de radiação, o tamanho prévio do tumor e o descolamento periosteal sugeridos como fatores potenciais.

ABSTRACT

Abstract Primary pyomyositis is a deep bacterial infection of the skeletal muscle. If left undiagnosed and untreated, the infection spreads, leading to sepsis, septic shock, and even death. The authors report a 23-year-old female presenting with piriformis pyomyositis during a treatment for Kikuchi-Fujimoto disease. Pyomyositis is a rare but potentially severe infection, which can lead to septic shock. The present case shows the need for a high degree of clinical suspicion for patients with compromised immune systems to begin treatment at an early stage. The literature demonstrates that outcomes of the treatment of piriformis pyomyositis are good.


Resumo A piomiosite primária é uma infecção bacteriana profunda do músculo esquelético. Quando não diagnosticada ou tratada, a infecção pode evoluir para sepse, choque séptico e até morte. Os autores relatam o caso de uma paciente do sexo feminino, 23 anos, apresentando piomiosite do músculo piriforme durante o tratamento da doença de Kikuchi-Fujimoto. A piomiosite é uma infecção rara, mas potencialmente grave, que pode levar ao choque séptico. Esse caso mostra a necessidade em se elevar o grau de suspeição clínica em pacientes com comprometimento do sistema imunológico, para que o tratamento seja iniciado em estágio precoce. A literatura mostra que os resultados do tratamento da piomiosite do piriforme são bons.

ABSTRACT

ABSTRACT OBJECTIVE: The objective of this study is to evaluate the efficacy of vascular reconstructive surgery after resection of bone and soft tissue tumors in extremities and the risk of progression to amputation. METHODS: This is a retrospective, observational data collection from medical records of patients who underwent resection of bone and soft tissue tumors in the period of 2002-2015. Thirteen patients met the inclusion criteria, which evaluated the correlations between certain factors (gender, tumor type, location, reconstruction, revascularization and patency, infection) with amputation in the postoperative period. RESULTS: In this study, of the 13 patients undergoing reconstruction, five (38.46%) evolved to amputation. All patients who progressed to amputation had the following in common: presence of bone sarcoma (p = 0.005), having undergone reconstruction with an orthopedic prosthesis (p = 0.005), lack of vascular patency in the revascularization site in the postoperative period (p = 0.032), and surgical site infection (p = 0.001). None of the patients with soft tissue sarcoma underwent amputation, and the only patient with bone sarcoma who did not undergo amputation had no infection and maintained vascular patency of the graft. CONCLUSION: The occurrence of infection appears to be one of the main risk factors for failure of revascularization, especially in cases of bone sarcoma in which vascular reconstruction is performed with placement of a non-conventional joint prosthesis.


RESUMO OBJETIVO: O objetivo deste estudo é avaliar a eficácia da cirurgia de reconstrução vascular após ressecção de tumores ósseos e tecidos moles em extremidades e o risco de evolução para amputação. MÉTODOS: Estudo retrospectivo, observacional, de coleta de dados em prontuário médico de pacientes submetidos a ressecção de tumores ósseos e de tecidos moles de 2002 a 2015; 13 pacientes preencheram o critério de inclusão, foram avaliadas as correlações de determinados fatores (gênero, tipo de tumor, localização, reconstrução, revascularização e patência, infecção) com amputação no pós-operatório. RESULTADOS: No presente estudo, dos 13 pacientes submetidos à reconstrução, cinco (38,46%) evoluíram com amputação. Todos os pacientes que evoluíram com amputação tinham em comum o fato de ser portadores de sarcoma ósseo (p = 0,005), ter sido submetidos a reconstrução com prótese ortopédica (p = 0,005) e não apresentar patência vascular no local da revascularização no período pós-operatório (p = 0,032), além de apresentar infecção no local da cirurgia (p = 0,001). Nenhum dos pacientes portadores de sarcoma de partes moles foi submetido à amputação e o único paciente do grupo com sarcoma ósseo que não sofreu amputação não apresentava infecção e mantinha patência vascular no enxerto. CONCLUSÃO: A ocorrência de infecção parece ser um dos principais fatores de risco para a falência da revascularização, especialmente nos casos de sarcoma ósseo em que a reconstrução vascular é feita juntamente com colocação de próteses articulares não convencionais.

ABSTRACT

Abstract Spore counts, species composition and richness of arbuscular mycorrhizal fungi, and soil glomalin contents were evaluated in a soil contaminated with Zn, Cu, Cd and Pb after rehabilitation by partial replacement of the contaminated soil with non-contaminated soil, and by Eucalyptus camaldulensis planting with and without Brachiaria decumbens sowing. These rehabilitation procedures were compared with soils from contaminated non-rehabilitated area and non-contaminated adjacent soils. Arbuscular mycorrhizal fungi communities attributes were assessed by direct field sampling, trap culture technique, and by glomalin contents estimate. Arbuscular mycorrhizal fungi was markedly favored by rehabilitation, and a total of 15 arbuscular mycorrhizal fungi morphotypes were detected in the studied area. Species from the Glomus and Acaulospora genera were the most common mycorrhizal fungi. Number of spores was increased by as much as 300-fold, and species richness almost doubled in areas rehabilitated by planting Eucalyptus in rows and sowing B. decumbens in inter-rows. Contents of heavy metals in the soil were negatively correlated with both species richness and glomalin contents. Introduction of B. decumbens together with Eucalyptus causes enrichment of arbuscular mycorrhizal fungi species and a more balanced community of arbuscular mycorrhizal fungi spores in contaminated soil.

ABSTRACT

Ainda hoje, pacientes que apresentam doença periodontal com lesões localizadas ou generalizadas causam inquietude por parte dos ortodontistas que, muitas vezes, recusam o tratamento devido às dúvidas sobre como os dentes reagirão às forças ortodônticas, supondo que haverá uma acentuação dos problemas, tornando-se ainda mais grave o quadro clínico. Entretanto, quando esse tipo de tratamento é abordado abrangendo outras disciplinas, com uma inter-relação do periodontista com o ortodontista, o que se tem visto são resultados satisfatórios em ambos os aspectos, ainda sim, superando expectativas estéticas do paciente. O objetivo desse trabalho foi descrever o tratamento ortodôntico realizado em uma paciente com o periodonto reduzido, porém, sem atividade de doença, e o resultado após dez anos de acompanhamento. Em resposta a um planejamento ortodôntico bem estruturado, ao uso de mecânica adequada e ao cuidado com as restrições do paciente, obteve-se sucesso na terapia ortodôntica, sem causar efeitos adversos nas estruturas de suporte em longo prazo.


Patients that present periodontal disease with local or general lesions still pose questions for orthodontists. Often, they refused to treat due to the lack of information regarding how teeth will react to orthodontic forces, assuming there will be an accentuation of problems. That attitude could make the clinical picture even worse. However, when this type of treatment is approached covering other disciplines, in cooperation between the periodontist and the orthodontist, the results were satisfactory in both aspects and still overcoming the aesthetic expectations of patient. The goal of this task is describing the orthodontic treatment in a patient with an assymptomatic, compromised periodontium and the follow-up after ten years of completion. In response to a well-structured orthodontic planning, the use of proper mechanics and care with patient's restrictions, success was obtained in orthodontic therapy, without causing adverse effects on long-term supporting structures.

ABSTRACT

OBJECTIVE: To evaluate the rate of local recurrence of extra-abdominal desmoid tumor and compare the outcomes of surgical treatment and conservative treatment. METHODS: Twenty one patients (14 women and seven men), mean age 33.0±8.7 years old, with a diagnosis of desmoid tumor were evaluated. The mean follow-up period was 58.5±29.0 months. Fourteen cases involved the lower limbs, four cases involved the upper limbs, and three cases involved the trunk. The average tumor size was 12.7±7.5 cm. Of the 21 patients, 14 did not undergo previous treatment and seven patients relapsed before the initial evaluation. Surgical treatment was performed in 16 patients and conservative treatment was performed in five patients. RESULTS: Recurrence occurred in seven patients (33%) and six of them relapsed within the first 18 months. No significant difference was observed between conservative and surgical treatment. However, a significant difference was observed among patients undergoing wide resection and who experienced improved local control. CONCLUSION: The recurrence rate of desmoid tumor was 33.3%. There was no difference in recurrence between conservative and surgical treatment. In surgical treatment, wide margins showed better results for recurrence control. Level of Evidence III.

ABSTRACT

ABSTRACT: Manure fertilization is a common practice, but little is known about its impacts on soil microbial activity and organic matter. Aiming to evaluate soil microbial response to nine years of successive applications of swine manure, organic carbon (TOC), total nitrogen (TN), pH, microbial biomass carbon (MBC), basal respiration (BR), metabolic quotient (qCO2), and enzyme (ß-glucosidase, phosphatase, arylsulphatase, and FDA) activities were measured in the 0-10cm soil layer, in a no-tillage system. Treatments were: control soil without fertilization (C), and application of two doses (104 and 209kg of N ha-1year-1) of urea (U1 and U2), pig slurry (PS1 and PS2) and deep litter (DL1 and DL2). TOC, TN, soil pH, MBC, and BR increased in soil fertilized with DL, and were lower in U treatments. Soils with U and DL application had higher qCO2, related to different sources of stressors like nutrient imbalance. Phosphatase and ß-glucosidase activities were not affected by treatments, increased with time, and had a strong correlation with MBC. We conclude that long-term swine manure applications increase microbial activity and soil organic matter, mainly in DL form; while urea applications have negative impacts on these indicators.


RESUMO: A fertilização com dejetos suínos é uma prática comum, porém, pouco se conhece acerca de seus impactos sobre a atividade microbiana do solo e a matéria orgânica. Com o objetivo de avaliar a resposta da microbiota do solo, após nove anos de aplicações sucessivas de dejetos suínos, foram mensurados o carbono orgânico total (TOC), nitrogênio total (TN), pH, carbono da biomassa microbiana (MBC), respiração basal (BR), quociente metabólico (qCO2) e a atividade enzimática (ß-glucosidase, fosfatase, arilsulfatase, e FDA), avaliações feitas na camada de 0 a 10cm de profundidade em um solo sob plantio direto. Os tratamentos foram: solo controle sem fertilização (C) e aplicação de duas doses (104 e 209kg de N ha-1ano-1) de ureia (U1 e U2), dejeto líquido (PS1 e PS2) e cama sobreposta (DL1 e DL2). O TOC, TN, o pH do solo, MBC e BR incrementaram no solo fertilizado com DL e foram mais baixos nos tratamentos com U. Os solos com aplicação de U e DL apresentaram o maior qCO2, relacionado a diferentes fontes de estresse, como o desbalanço de nutrientes. A atividade da fosfatase e da ß-glucosidase não foi afetada pelos tratamentos, mas incrementou com o tempo e teve uma forte correlação positiva com o MBC. Conclui-se que as aplicações de dejetos suínos em longo prazo incrementaram a atividade microbiana do solo e o teor de matéria orgânica, principalmente quando aplicados na forma de DL, enquanto que as aplicações de U apresentaram impactos negativos sobre esses indicadores.

ABSTRACT

Abstract High copper (Cu) levels in uprooted old vineyard soils may cause toxicity in transplanted young vines, although such toxicity may be reduced by inoculating plants with arbuscular mycorrhizal fungi (AMF). The objective of this study was to evaluate the effects of AMF on the plant growth, chlorophyll contents, mycorrhizal colonization, and Cu and phosphorus (P) absorption in young vines cultivated in a vineyard soil contaminated by Cu. Commercial vineyard soil with high Cu levels was placed in plastic tubes and transplanted with young vines, which were inoculated with six AMF species (Dentiscutata heterogama, Gigaspora gigantea, Acaulospora morrowiae, A. colombiana, Rhizophagus clarus, R. irregularis) and a control treatment on randomized blocks with 12 replicates. After 130 days, the mycorrhizal colonization, root and shoot dry matter (DM), height increment, P and Cu absorption, and chlorophyll contents were evaluated. The height increment, shoot DM and chlorophyll contents were not promoted by AMF, although the root DM was increased by R. clarus and R. irregularis, which had the greatest mycorrhizal colonization and P uptake. AMF increased Cu absorption but decreased its transport to shoots. Thus, AMF species, particularly R. clarus and R. irregularis, contribute to the establishment of young vines exposed to high Cu levels.

ABSTRACT

O número de atletas de desportos de contato é alto, portanto, os acidentes de face nesses esportes também possuem um índice elevado. Porém, a procura por protetores bucais é inferior à necessidade de uso, devido à falta de informação. O presente trabalho procurou demonstrar a confecção de um protetor bucal do tipo III, relatar a prevenção quanto ao risco de traumatismos dentoalveolares, faciais e articulares, e ressaltar sua importância nos desportos de contato e a falta de orientação aos atletas. Concluiu-se que o uso do protetor é necessário em todos os esportes de contato, que o protetor bucal do tipo III é superior em relação aos demais e que o ideal seria a presença de profissionais da área da saúde nas equipes esportivas para que pudessem evidenciar a necessidade do uso de protetor bucal e, consequentemente, reduzir o número de lesões no complexo bucofacial...


The number of athletes in contact sports is high, so accidents face these sports also have a high index. However, demand for mouthguards is less need to use due to lack of information. This work demonstrates the making of a mouthguard type III report the prevention of the risk of dentoalveolar trauma, facial and joint; emphasize on its importance in contact sports and the lack of guidance to athletes. We conclude that the use of the shield is necessary in all contact sports, the mouthpiece of the type III is higher than the other, the ideal would be the presence of health professionals in sports teams so they could show the need to use a mouthpiece and hence reduce the number of lesions in the orofacial complex...

ABSTRACT

The pH of the culture medium directly influences the growth of microorganisms and the chemical processes that they perform. The aim of this study was to assess the influence of the initial pH of the culture medium on the production of 11 low-molecular-weight organic acids and on the solubilization of calcium phosphate by bacteria in growth medium (NBRIP). The following strains isolated from cowpea nodules were studied: UFLA03-08 (Rhizobium tropici), UFLA03-09 (Acinetobacter sp.), UFLA03-10 (Paenibacillus kribbensis), UFLA03-106 (Paenibacillus kribbensis) and UFLA03-116 (Paenibacillus sp.). The strains UFLA03-08, UFLA03-09, UFLA03-10 and UFLA03-106 solubilized Ca3(PO4)2 in liquid medium regardless of the initial pH, although without a significant difference between the treatments. The production of organic acids by these strains was assessed for all of the initial pH values investigated, and differences between the treatments were observed. Strains UFLA03-09 and UFLA03-10 produced the same acids at different initial pH values in the culture medium. There was no correlation between phosphorus solubilized from Ca3(PO4)2 in NBRIP liquid medium and the concentration of total organic acids at the different initial pH values. Therefore, the initial pH of the culture medium influences the production of organic acids by the strains UFLA03-08, UFLA03-09, UFLA03-10 and UFLA03-106 but it does not affect calcium phosphate solubilization.

ABSTRACT

INTRODUCTION: Depressive disorders (DDs) are very prevalent disorders particularly in women, a high-risk gender group. Determining the risk and protective factors associated with the development of DDs is fundamental to planning preventive and therapeutic strategies. In this study, we evaluated the correlations between healthy maternal attachment and the development of DDs in adulthood. METHODS: We evaluated 52 women at 6 months to 1 year after premature childbirth at Maternidade Vila Nova Cachoeirinha. They were evaluated using the following instruments: Brazilian Criteria of Economic Classification, Parental Bonding Inventory (PBI), Center for Epidemiologic Studies Depression Scale (CES-D), and Edinburgh Postnatal Depression Scale (EPDS). Cut-off scores on the CES-D and EPDS were used to classifythe subjects as currently having a DD or having probable postpartum disorder (PPD) after childbirth. Multiple logistic regression was used to evaluate the risk factors associated with DDs. RESULTS: We found that 49.1% of the sample had a current depressive episode, and 73.6% had probable PPD. Based on logistic regression, current depression (odds ratio = 1.092 [confidence interval: 1.005; 1.186]), and a PPD (odds ratio = 1.108 [confidence interval: 1.011; 1.21]) were negatively correlated with affective maternal relationships. CONCLUSIONS: Women who reported healthy attachment with their mothers did not develop DDs when faced with stressful situations such as premature childbirth.

ABSTRACT

OBJETIVO: Avaliar a reprodutibilidade intraobservador e interobservador da classificação proposta pelo grupo AO/ASIF, para as fraturas dos ossos longos em crianças. MÉTODO: Foram analisadas e classificadas por cinco avaliadores, 100 radiografias convencionais digitalizadas de fraturas dos ossos longos em crianças, utilizando a classificação alfanumérica proposta pelo grupo AO/ASIF. A força de concordância intraobservador (realizada com intervalo de 90 dias) e a interobservador foram avaliadas através do coeficiente Kappa. RESULTADOS: O índice Kappa para observação intraobservador foi de 0,69 (grande concordância) e na análise interobservador o índice foi de 0,64 (grande concordância) na primeira avaliação e 0,61 (grande concordância) na segunda análise realizada 90 dias após a classificação inicial. CONCLUSÃO: A classificação proposta pelo grupo AO/ASIF mostrou grande concordância intra e interobservador, sendo útil para utilização nas fraturas dos ossos longos em crianças.


OBJECTIVE: To evaluate the interobserver and intraobserver reproducibility of the classification proposed by the AO/ASIF group for long bone fractures in children. METHODS: One hundred roentgenograms of long bone fractures in children were evaluated and classified according to the alphanumeric AO/ASIF classification by six observers. The strength of theintraobserver(performed with a 90-day interval) and interobserveragreementwere evaluated using the Kappa coefficient. RESULTS: The intraobserver Kappa index was 0.69 (good agreement). The interobserver index was 0.64 (good agreement) in the first evaluation and 0.61 (goodagreement) in the second analysisperformed 90 days after the initial classification. CONCLUSION: The classification proposed by the AO/ASIF group for long bone fractures demonstrated good inter- and intraobserver agreement. This classification is useful for describing fractures of long bones in children.

ABSTRACT

Introdução: A Mucopolissacaridose é uma patologia metabólica, hereditária, causada por erros inatos que determina a diminuição ou inativação de atividades enzimáticas e causa alterações em todos os sistemas, a exemplo da rigidez articular. Objetivo: Avaliar a função motora de pacientes com MPS por meio da amplitude de movimentos ADM, após aproximadamente um ano de tratamento com terapia de reposição enzimática TRE. Métodos: Foram avaliados 18 meninos e 4 meninas: 11 MPS VI, 3 MPS I e 8 MPS II. De acordo com a GMSCF (classificação motora funcional, três pacientes apresentavam nível funcional cinco, um com nível quatro, um nível três, três nível dois e 14 com nível funcional um. Após aproximadamente um ano de TRE, os pacientes foram reavaliados por goniometria para verificar se houve melhora da função motora.Resultados: Não houve modificação estatisticamente significante em nenhum parâmetro de mobilidade, excetuando-se a flexão dos ombros que mudou de 59,8 direito e 62,2 esquerdo para 78,5 direito e 80,2 esquerdo, com p de 0,017 e 0,036, respectivamente. Tanto os portadores de MPS II como os de MPS VI apresentaram melhora clínica da flexão dos ombros. Quando analisados por grupo de MPS (VI e II), a melhora da ADM não foi significante. Este fato, entretanto, pode ser resultado da diminuição do número de pacientes quando a análise é feita por subgrupos de MPS.Conclusão: A função motora medida pela ADM em pacientes com MPS após um ano de TRE apresenta pouca melhora clínica, mas foi possível detectar sinais de aumento da ADM na articulação do ombro.


Introduction: Mucopolysaccharidosis is a metabolic disease, hereditary, caused by inherited errors that determine the reduction or inactivation of enzyme activity and causes changes in all systems, such as joint stiffness. Objective: Evaluate the motor function of patients with MPS through the range of movements ROM, after approximately one year of treatment with enzyme replacement therapy ERT. Methods: 18 boys and 4 girls were evaluated: 11 MPS VI, 3 MPS I and 8MPS II. According to GMSCF motor functional classification, three patients had functional level five, one with level four, one at level three, three at level 2 and 14 with functional level one. After about a year of ERT, patients were evaluated by goniometry to determine whether there was improvement in motor function. Results: No statistically significant change in any parameter of mobility, except for the flexing of the shoulders that changed from 59.8 right and 62.2 left to 78.5 right and 80.2 left , with p equals 0.017 and 0.036, respectively. Patients with MPS II and MPS VI showed clinical improvement in shoulder flexion. When analyzed by MPS group VI and II, the improvement in the ROM was not significant. This fact, however, may result from the decreased number of patients when the analysis is done by MPS subgroups. Conclusion: The motor function measured by the ROM in patients with MPS after one year of ERT has little clinical improvement, but it was possible to detect signs of increased ROM in the shoulder joint.

ABSTRACT

OBJETIVO: Avaliar uma série de casos de luxação traumática posterior em crianças, o tratamento e os resultados, e revisar os aspectos relacionados à sua epidemiologia, diagnóstico clínico e radiográfico, tratamento, complicações e prognóstico. MÉTODOS: Foram avaliados retrospectivamente cinco pacientes com luxação traumática do quadril com média idade de 4,6 ± 0,9 anos e tempo de seguimento de 19,8 ± 7,0 meses. Foram avaliados o tempo entre a luxação e a redução, o tipo de tratamento, as lesões associadas e as complicações tardias. RESULTADOS: O tratamento inicial foi a redução incruenta com tempo médio de 5,2 ± 3,6 horas após o trauma inicial, sendo que todos foram submetidos à redução sob anestesia. O tratamento complementar incluiu imobilização gessada e tração. Não foi observada necessidade de cirurgias adicionais ou sequelas a longo prazo. CONCLUSÃO: A luxação traumática do quadril deve ser tratada com redução incruenta rápida, controle adequado da redução e observação rigorosa para diagnóstico e tratamento de complicações tardias.


OBJECTIVE: To evaluate a series of cases of traumatic posterior dislocations in children, the treatment and the results, and to revise aspects such as the epidemiology, clinical and radiographic diagnosis, treatment, complications and prognosis. METHODS: Five patients with traumatic hip dislocation, with an average age of 4.6 ± 0.9 years, and an ongoing follow-up period of 19.8 ± 7.0 months, were evaluated retrospectively. The time between dislocation and reduction, the type of treatment, associated injuries, and subsequent complications were also evaluated. RESULTS: The initial treatment was closed reduction, in an average time of 5.2 ± 3.6 hours after the initial trauma, in which the patients were subjected to the reduction under anesthesia. Complementary treatment included immobilization with casts and traction. No needs for additional surgeries or long-term side effects were observed. CONCLUSION: Traumatic dislocation of the hip should be treated by quick closed reduction, with appropriate control of the reduction and careful observation of the patient for diagnosis and treatment of subsequent complications.

ABSTRACT

Objetivo: descrever o perfil clínico-epidemiológico de pacientes com o diagnóstico de AVE admitidos no Hospital Pronto Socorro Municipal - Mario Pinotti - Belém, PA. Método: realizou-se um estudo transversal analítico, por meio de questionário padronizado e consulta de prontuários médicos de 123 pacientes internados entre outubro de 2006 a março de 2007, com diagnóstico de AVE. A significância estatística definiu-se baseada no uso do software Epi Info versão 6.04 d. Resultados: dos 123 pacientes incluídos nos estudo, a maioria apresentou idade entre 70 e 79 anos(26,8%); sexo masculino (56,1%); procedência do município de Belém (45,5%); aposentados (52,0%); possuindo ensino fundamental incompleto (57,7%); renda mensal de um salário mínimo (48,8%); hipertensão arterial sistêmica (87%); diabetes mellitus (23,6%). A seqüela predominantefoi a hemiparesia (86,2%), seguida de afasia (46,3%), tontura (43,1%). Conclusão: o perfil da população estudada não difere daquele, usualmente, encontrado na literatura; homens de baixarenda, idade avançada e hipertensos, constitui o maior grupo de risco para ocorrência do AVE.
